Chile pepper domestication investigated

I haven’t read the paper on Capsicum annuum domestication by Seung-Chul Kim and colleagues in the June 2009 issue of the American Journal of Botany, but the EurekAlert piece on it is definitely intriguing. I was particularly struck by the finding that genetic differentiation between geographically distant populations is higher for the cultivated than for the wild species. That may be because people don’t move pepper seeds nearly as far as birds. Also, it seems this particular pepper should be included in the lengthening list of crops that were probably domesticated in more than one place. Need to get that pdf.
